Ahelicopter flies 250 km on a straight path in a direction 60° south of east. the east component of the helicopter's displacement is km.

The helicopter is flying in a direction 60 degrees south of east. Its displacement (250 km) corresponds to the hypothenuse of a right triangle, where the components of the displacement in the east direction corresponds to the side of the triangle adjacent to the angle. Therefore, the east component of the displacement can be found as
